AIR CONDITIONING APPARATUS 1,9 In ventor Patented Oct. 10, 1939 UNITEDSTATES PATENT OFFICE 1 Claim.

This invention relates to air conditioning apparatus, and has for theprimary object the provision of an efficient 'and inexpensive portabledevice of this character which may be readily set up in a room forconditioning the air therein by removing foreign matter from the air andfor either cooling the air or for heating the air depending on which waythe apparatus is arranged for operation and also will humidity the air.

With these and other objects in view, the invention consists in certainother novel features of construction, combination and arrangement ofparts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which Figure lis a front elevation illustrating an air conditioning apparatusconstructed in accordance with my invention.

Figure 2 is a side elevation illustrating the same.

Figure 3 is a vertical sectional view illustrating the device.

Figure 4 is a transverse sectional view illustrating the device.

Referring in detail to the drawings, the numeral 5 indicates a cabinetpreferably having grill and scroll work to add to the artisticappearance of the cabinet. The cabinet has a portion of its front wallstruck out to form a series of louvers 6 to permit air to escape fromthe cabinet. The rear wall of the cabinet .directly opposite the louversis provided with an opening for the purpose of permitting air to enterthe cabinet and has`preferably arranged therein a filter 1. The lter 'Imay be of any desired construction, preferably consisting of spacedforaminous material 8 with a fibrous material 9 arranged therebetween sothat air passing therethrough will be freed of all foreign matter.

Horizontal spaced walls I0 and I I are arranged in the cabinet to forman air space I2 arranged between the louvers and the filter and in whichis mounted an electric motor I 3 for the purpose of driving a fan Il.The fan when in operation will draw air through the filter and expel theair by way of the louvers. It isl also preferable to have arrangedbetween the louvers and the fan I 4 a foraminous material I5 acting tointercept any foreign matter that may be in the air after Lpassingthrough the lter and also to act as an air moistener vby having asuitable liquid discharged thereon by a device I6. The detailconstruction of this device is immaterial as far as the presentinvention is concerned. It will, therefore, be seen as the air passesthrough the .foraminous material I5 it will collect a certain vamount ofmoisture to humidify the air.

A radiator core I1 is arranged in the space I2 and is preferably of thehoney-comb construction and the upper end thereof is in directcommunication with a water chamber I8 formed in the upper portion of thecabinet. The water chamber I8 besides containing water is also adaptedto have ice placed therein for the purpose of cooling or chilling thewater. The outlet for the radiator core I`I is preferably in the form ofa neck I 9 forming a part of a catch basin 20 -arranged in the bottom ofthe cabinet. The catch basin has a drain valve I9.

Mounted in the space I2, adjacent the fan I4 is a pump 2l driven by theelectric motor I3'. 'I'he pump 2I is connected to the catch basin 20 bya pipe 22. Also connected to the pump 2l is a pipe 23 which extends intothe water chamber I8 so that when the pump 2| is in operation water willbe drawn from the catch basin and returned to the water chamber afterbeing circulated through the radiator core. The fan propels the airthrough the radiator core so that the air will be cooled on leaving thecabinet by way of the louvers also being free of foreign matter besidescontaining a desired amount of moisture.

An electric heating element of a water-proof construction and indicatedby the character 25 is arranged in the water chamber I8 and may beconnected to an electric source (not shown) in any well known manner.Whenever it is desired to change the operation of the device from aircooling arrangement it is only necessary to discontinue the placing ofice in the water chamber I8 and to heat the water therein by theelectric heating element 25. the chamber I 8 passing through the core ofthe radiator will raise `the temperature of the air for the purpose ofheating the room in which the device is located.

In order that the temperature in the room may f be automaticallycontrolled a conventional type of thermostat 26 is arranged exteriorlyof the cabinet and electrically connected in the circuit of the motorI3. Also the thermostat 26 may be connected in the circuit of theelectric heating medium 25 when the device is to be employed for heatingthe air. When thethermostat 26 calls for heat the electric motor will beset in operation aswell as the electric heating element 25. Of course,when the device is to be employed The heated water in i iii :for coolingthe air the thermostat 26 will be iisconnected from the circnit ci theheating element 25 and then will only control the operation of theelectric motor H3.

Through the use of the radiator core a com= paratively large area isprovided for the air 'to contact on its passing; through the cabinet soas to be either coolei or heated depending in which way the apparatus isarranged for o n=- eration.

- The louvers (i while being shown as ireoi on the cabinet they may beremovably mounted there@ on so that they may be readily adjusted to varythe direction oi heated air leaving the cabinet.

it is believed that the foregoing description, when taken in connectionwith the drawings will fully set forth the construction and advantagesof this invention to those skilled in the art to which such devicesrelate so that further detailed description will not be necessary.

What l claim is:

An air conditioning apparatus comprising a vertically arranged portablecabinet including upper anni lower finiti compartments and; an airchamber arranged between said compartments, one vertical wail of thecabinet having an opening to admit air to said chamber, a nlter mountedon the cabinet within the opening to remove foreign matter from the airentering the cham*- ber, louvers formed in another vertical wall of thecabinet to permit air to escape from the chamber, air circulating meansin the chamber, a heat exchange core connecting the compartments andarranged between said air circulating means and the louvers for the airto pass through from said opening before reaching the louvers, ahumidifying sheet of material` arranged between the core and theiouvers, power means in the chamber for operating the air circulatingmeans, and a pump connected to said compartments for the circulation offluid from the lower compartment to the uriner compartment and driven bysaid power means l WIL TLJAM NEUBERT.
